Description

While attempting to build GHC 6.6.1 via ​MacPorts, I received the following traceback. Apologies for the length of the transcript, but I'm not sure how much of it will be needed to diagnose the trouble.

I'm not sure if this is a fault with GHC itself, or an interaction with MacPorts, though the message "ghc-6.4: internal error: evacuate: strange closure type 32782" led me to suspect the former.
